- A child is standing on the edge of a cliff overlooking a river. The cliff is 8 m above the edge of the river and the river is 20 m wide where the child is located. If the child can throw a rock with a speed of 20 m/s, will the rock make it across the river?A typical hard disk in a desktop computer is a uniformly solid, 400 gram disk 3.5 inches in diameter, and takes 70 milliseconds to spin from rest up to a frequency of 7200 revolutions per minute (r.p.m.). Problem 2.1. What is the period of the disk in seconds when it’s at its final spinning rate? Problem 2.2. What is its angular speed in rad/s when it’s at its final spinning rate? Problem 2.3. Assuming it is constant throughout this spin-up process, what is the angular acceleration of the disk in rad/s2?In 2014, the Rosetta space probe reached the comet Churyumov– Gerasimenko. Although the comet’s core is actually far from spherical, in this problem we’ll model it as a sphere with a mass of 1.0 x 1013 kg and a radius of 1.6 km. If a rock were dropped from a height of 1.0 m above the comet’s surface, how long would it take to hit the surface?
- A high-speed drill reaches 2000 rpm in 0.60 s. Through how many revolutions does it turn during this first 0.60 s?A light rod is 88 cm long. Its top end is pivoted on a low-friction horizontal axle. The rod hangs straight down at rest with a small massive ball attached to its bottom end. You strike the ball, suddenly giving it a horizontal velocity so that it swing around in full circle. What minimum speed (m/s) at the bottom is required to make the ball go over the top of the circle? Round your answer to 2 decimal places.Pool players often pride themselves on their ability to impart a large speed to a pool ball. In the sport of billiards, event organizers often remove one of the rails on a pool table to allow players to measure the speed of their break shots (the opening shot of a game in which the player strikes a ball with his pool cue). With the rail removed, a ball can fly off the table, as shown in the figure. h d The surface of the pool table is h = 0.750 m from the floor. The winner of the competition wants to know if he has broken the world speed record for the break shot of 32 mph (about 14.3 m/s). If the winner's ball landed a distance of d = 5.15 m from the table's edge, calculate the speed of his break shot vo. Assume friction is negligible. m/s
